` Proceeding vnow .to the description of the drawings, the'num'erall indicates' a flushing tank of the usualjtype within which 1s mounted" a Siphon outlet valve designated as an entirety Fig. .1 by the'l numeral 2.

The ',siphonincludes a vertically mounted-v 'stati'onary tube-3, va vertically-movable tube- 4v and a' sealing` tube 5, thel latter' member Ibeing mounted in fixed Vrelationto the 'tube' 4 and adapted: for corresponding vertical sliding movementtherewith. vThe tube "3 is open'at'each end and'intermediatejits g Apparatus, .of' which the follow- Aingl iis-'aA specification. f-

length is provided with the circumferentiallyspa'ced,` longitudinally extending ,openings 6, provided for a purpose to be hereinafter disclosed. A discharge pipe "7 is mounted in al suitable orifice formed in the bottom wall 8 of'l the tank and is pro-` Patented oet. efe, 1915;I

vided -with an annular outwardly extending shoulder 9 formed adjacent :the upper end and is vfurther provided with a circular recess wherein is seated the lower end of'the tube 3. A washer 10 is mounted on the top of the member'7 andencircles thetube 3. This washer may be made of any suitable pliable material such as leather, liber yor A washer 11 of similar nature risv ldisposed between the shoulder 9 and the rubber.

wall S to insure the sealing of the'joint. A

flock nut 1 2,I is mounted in screw threaded engagement with the pipe 7 and bears against the under face ofthe wall 8, 'thusv holding the member 7 securely in the. desired position. The tube fl incases the tube 3 and isi'n turn incased by the sealing cyl-I inder 5, the outer wall of the member 4 being l.spaced from the inner Wall ofthe member' 5. ,The member 4f carries a lead Washer ".13 ati its lower end and at` its upper end is Vexte'riorly screw threaded to receive the projecting .cap 1.4. This 4latter member is essentially a metallic cap carrying a diametrically positioned-.bail member 15 which is formed with a centrally positioned internally screw threadedoriice 16 provided to receive the screw threaded connecting rodv 17. lock nut 1S is screw `threaded on the member 17 and acts to hold the-bail'member 15 in rigid relation to the top 19 of the member 5, thus maintaining vthe tube 4 in spaced relation to the inner wall of the tube 5. A lever 2O pivotally mounted as at 21 and vprovidedwith an operating cable 22 is pivotally connectedv tothe member 17 as The p construction and arrangement 4of parts of the invention being thus disclosed, v

I now pass to the description of the operation'of the device. 4. A

Presuming the tank to be filled .with water .as indicated in Fig. 1 and the tubes' 4 and 5 -in the position indicated inl dotted lines in Fig. 2, it will be seen .that a pull eXerted upon the lever will result in the upward .I'novemen't of the sealing cylinder 5 and the ltube 4l.V l/Vhen the tube t has reached the po- 'sition illustrated in Fig. 2, it is apparent "that water will rush into the tube 3 through lireventinrq,` Water from entering into the tubes; However, at the movement of the final sealing of the openings G, there will be a quantity of Water in tbe tube 3 and as this Water exhausts troni the tube 3 a partial vacuum will be created7 thus starting' the siplionic action-of iny device. The opening G being closed, the Water issues from the tank by siplionie action as indicated by the arrows in Fig. 2, until tliewater falls 'below the lower end of the tube i ln reduction to practice, I have tound that the forni of niy invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most ellicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor AChanges in details of construction,

proportion 'and arrangement of paris may `be resorted to, When required, as deiined in the appended claim.
